Confused, have a 1995 Saab 9000 CSE 2.0 LPT.
The 'check engine' light became illuminated after a local centre fitted a new downpipe.
It flashed 6 times so I got the Oxygen Sensor changed. All that was available at short notice was a universal 3 wire one. It was wired in but still has the light illuminated and it still flashes 6 times, disconnected the battery to try and reset ECU, worked for about 5 mins. Light came on after reversing out of my drive.
Some saab sites says that Trionic systems can't use the flashing lights as a diagnostic tool.
I have measured Pins 1 and 2 (the white ones) on the oxy sensor (as recommended by the Haynes Book of lies) and it measures 7ohms (recommended maximum 10ohms).
Anyone offer any advice?
Cheers

i had this problem with one of my 9000, coincidentally it happened right after i fitted a new down pipe, i like youself went for the lamnda sensor but a new one proved ok,it turned out to be the ezk ignition module, why this happened when i changed the downpipe i dont know,i fitted a motorcraft equivalent to the bosch as it was £80.00 new,I dont know if your saab has that ignition system on it though maybe some of the other guys might know,
cheers Ricky

Cheers Richard,
I'm not sure if mine has the same system as yours did. It has a red DI cartridge if that helps.
I will have a look at the Haynes Book of Lies again and see what I can find out, thanks again,
Wayne
